"InvalidOperationException: Expected 1 bit per pixel only here" when opening RTF file

rtf2.zip (5.7 KB)

When opening an RTF file with Aspose.Words.dll (version 21.7) the following error occurs:

  Message=The document appears to be corrupted and cannot be loaded.
   at Aspose.Words.Document.(Stream , LoadOptions )
   at Aspose.Words.Document.(Stream , LoadOptions )
   at Aspose.Words.Document..ctor(Stream stream, LoadOptions loadOptions)

Inner Exception 1:
InvalidOperationException: Expected 1 bit per pixel only here.

The code used for opening the file is as follows:

var document = new Aspose.Words.Document("rtf2.rtf");

Please find attached the problematic file. It is in fact not corrupted because MS Word opens it and displays it correctly.

Let us know if we can expect a fix for this.
